ABSTRACT:
Sensitive rotating viscometers which include a head, rotor and stator, for example, a Brookfield viscometer, and have their head supported by a hollow housing and their stator held in place by the same hollow housing are improved by an internally threaded wall in a lower portion of the hollow support member, having means to exert guiding pressure on a means to accept pressure of a correspondingly, externally threaded nut, the correspondingly, externally threaded nut for attachment within the internally threaded wall, which threaded nut has an extension which is perforately slotted, the nut extension having the means to accept pressure, so as to cause the nut extension to be directed inwardly by tightening of the nut within the internally threaded wall, so as to cause snug contact between the lower interior surface of the hollow support member and the exterior cylindrical surface of the stator. The device may be embodied as a separable collar housing and stator/tube collar with such an aforesaid nut.
